Application tiled January 5, 1912. Serial No. 6693566.

To all whom t may concern:

Be it known that I, Ancre L. HANSEN, citizen of' the United States,residing at Evanston, in the county of Cook and State of illinois, haveinvented certain new andV useful Improvements 1n Massage Devices;-

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention has for its object to provide an improved manuallyoperated vacuum massage device, and consists in the features ofconstruction and combinations of' parts hereinafter fully described andparticularly claimed.

In the accompanying drawings illustrating a suitable embodiment of theinvention: Figure -lis a side elevation of a device constructed inaccordance with the invention. F ig. -2- is a central longitudinalsection of the same on the line 2-2 of Fig-1 My invention has for itsmain object to provide a massage device which is easily operated toproduce a relatively high degree of vacuum and in which the pressureexerted by the hands in operating the device serves to press the nozzleagainst the portion of the body to which it is applied.

rIhe device comprises the cylinder A which terminates at its upper endin a tapered end portion B having a central opening through which therod C of the piston D passes `which is reciprocably movable in saidcylinder. TNithin said tapered portion'B is a plate or head E having atapered flange F, said head E serving as a seat for one end of thehelical spring G which bears upon the piston at its other end tomaintain the latter normally at the lower limit of its movement. Thepiston D may be constructed in any convenient manner and is providedwith a cup washer H by means of which a fluid-tight joint between thepiston and the inner circumferential wall of the cylinder is maintained.Mounted upon said cylinder or casing externally of the same is a ring Icarrying two diametrically opposite projections J to which two handlevers K are pivotally secured by means of screws L passing throughopenings in the free ends of the arms M of said levers K. Each of saidlevers K is connected with the piston rod C,

adj acentthe upper end thereof, by means of a pair of toggle levers Nwhich are pivotally secured at one end to said piston rod C and at'their other ends to said respective hand levers K in any suitablemanner, the pivotal connections thereof with said levers K beingdisposed at a lower elevation or nearer adjacent the cylinder than thepivotal connections thereof with said rod C, when the latter is disposedat the lower limit of its movement, whereby, when said hand levers aremoved toward each other, relative reciprocal movement will be impartedto the cylinder and piston against the action of said spring. The saidcylinder A. is open at one end and said open end portion is adapted toreceive sleeves O, preferably made of rubber, and which may be providedwith nozzles of various shapes and sizes depending upon the purpose forwhich the same are adapted to be used and the parts of the body or placethereon to which the same may be intended to be applied. Said sleeves Oare slipped over the open end portion of said cylinder A and are held inplace thereon by friction and by the vacuum produced within the cylinderwhen the mouth portions of said nozzles are applied to the skin and thepiston is moved by moving the hand levers K toward each other. The saidhand levers K are preferably provided with roughened or lrnurled outerfaces to prevent a slipping of the hands thereon while operatin` thedevice, and are preferably also equipped with tangibly appreciable meanssuch as the curved arms P adapted to engage one or more lingers of thehand to maintain the latter in a desirable position for exerting amaximum leverage when operating the device.

rlhe operator may obviously move; the piston to any desired extent toproduce a vacuum within the cylinder of such degree as may be desired.The relative positions of the several parts of the device are such aswill cause the nozzles to bear more firmly on the skin as the levers Kare moved toward each other without causing the cylinder to turn on itslongitudinal axis during suoli movement, this being essential to theproduction of the best results.

The device is very simple, ecient and easily operated.

I claim as my invention:

A massaging device comprising a cylinder,

llO

a pistonY slidable therein, a spring resisting the movement of thepiston in one direction, manually operable means for moving the pistonagainst the resistance of said spring, a flexible tubular extension Jforthe mouth of the cylinder, and guard means associated With said manuallyoperable means for preventing a slipping of the hand operating thelatter, said guard means enabling the userV simultaneously to operatethe piston and to force the said extension rmly against the skin surfaceWhich is being massaged, said manually operable means including a pistonrod and levers pivoted upon the cylinder at opposite sides of said rodsubstannesses. v v
